IEC 60364-7-740:2000

Overview

IEC 60364-7-740:2000 is an essential international standard published by the International Electrotechnical Commission (IEC) that defines the requirements for temporary electrical installations in special locations such as fairgrounds, amusement parks, circuses, and similar environments. This standard applies to mobile, temporary, or permanently installed electrical machines and structures incorporating electrical equipment. The focus is on ensuring safe design, installation, and operation of these installations, which are repeatedly installed and dismantled without compromising safety.

This standard supplements and modifies general electrical installation regulations outlined in the IEC 60364 series, specifically focusing on temporary structures, amusement devices, and booths in dynamic, public entertainment settings. It emphasizes minimizing electrical hazards while facilitating the practical needs of mobile and semi-permanent setups.

Key Topics

• Scope and Application
  IEC 60364-7-740 outlines minimum safety requirements designed to accommodate the unique challenges of electrical installations subjected to frequent installation and removal. It excludes requirements for the electrical equipment inside machines, referencing IEC 60204-1 for those specifics.

• Safety and Protection Measures
  The standard mandates protective measures against electric shock, considering the external influences typical for outdoor and temporary settings. It guides on the correct implementation of safeguards ensuring safety under varying environmental conditions.

• Equipment Selection and Installation
  It covers the selection, erection, and verification of electrical components, including wiring systems, switchgear, and other relevant equipment adapted to temporary or mobile use. This includes requirements for mechanical stability, resilience, and ease of installation.

• Verification and Compliance
  Verification procedures are detailed to ensure electrical installations meet all prescribed safety standards before operation. Regular inspections and adherence to maintenance rules are fundamental for ongoing safety.

• Reference to Related Norms
  IEC 60364-7-740 aligns with and supplements provisions of IEC 60364, while coordinating with IEC 60204-1 on electrical machinery equipment safety. It also recognizes non-electrical safety standards such as those developed by CEN TC 152.

Applications

This standard is critically important for a diverse range of temporary and mobile electrical installations, including:

• Electrical setups for fairground rides, amusement devices, and booths
• Temporary power and lighting installations at amusement parks
• Mobile electrical machines and structures used in circuses, traveling shows, and festivals
• Any repeated installation of electrically powered amusement or exhibition structures at public events

By adhering to IEC 60364-7-740, operators and installers ensure the reliability, safety, and compliance of electrical installations in environments that present unique operational and safety challenges due to their temporary nature and public access.
